iMPRovED BED-Borrow?.

Specification forming part of Letters Patent No. 33,65, dated i{o\'cmbcr 5, lStil.

To @ZZ whom it may concern:

Be it known that I, O. A. A. ROUILLION, of the city, county, and State of N ew York, have invented a new and Improved Spring Bed- Bottom; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a longitudinal vertical section of my invention, taken on the line a x, Fig. 2; Fig. 2, a planor top view of the same; Fig. 3, a transverse vertical section of the same, taken in the liney y, Fig. 2.

Similar letters of reference indicate corresponding parts in the several gures.

The object of this invent-ion is to obtain a spring or elastic bed-bottom of simple construction, which will be more iiexible than those hitherto devised, and which will admit of being used with a very thin mattress or bed.

The invention consists in constructing the bed-bottom of a series of spiral springs connected together and forming one or more layers, as hereinafter shown and described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular frame constructed of such dimensions as to tit in the bedstead and iill the space within the head and foot rails and the side rails. To this frame A the bed-bottom is attached. The bed-bottoni is formed of a series of spiral springs, a, which may be constructed oi any suitable wire, iron, steel, copper, or composition. The springs may be abouthalf an inch in diameter. That would probably be the most desirable size; but they maybe greater or less, as circumstances require, and the wire maybe of any suitable thickness, according to the size of the bed-bottom or the weight it is designed to sustain. The springs a are interloclied or twisted one within the other, as shown clearly in Figs.

2 and 3, so as to forma complete wire bottom, Y

which covers the upper part of the frame A. The ends of the springs c may be secured to the end pieces, b b, of the l'rame A by means of cleats or leather strips cc, which are nailed on the upper edges of b b,with the ends of the springs a beneath them. rPhe springs a at the sides of the bed-bottom are iitted on rods d d, which are secured one to each side piece, e, of the frame A, as shown in Figs. 2 and 3. There may be two or more layers of the springs a, one over the other. Two layers are shown in the drawings, the springs at the sides of the lower layer being connected to springs near the sides of the upper layer, as shown atff in Fig. 8.

A bed-bottom thus constructed is extremely exible, yielding or giving to the movement of every limb of the occupant and conforming perfectly to the shape or position ot' the body.

A very thin mattress only is required for the bottom, owing to its extreme ilexibility or yielding tendency.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- V An elastic bed-bottom constructed of a series of spiralsprings interlocked or connected together to form one or more layers or bottoms, one over the other, and attached to a suitable frame, substantially as shown and described.
